Which do you recommend and why?

I have used both to do essentially the same thing when pulling results from a database. I looked it up on php.net and there seems to be a split over which is better to use. So I just wanted to get some opinions here.

Foreach works specialy for arrays:
foreach($myArray as $value) { }

While something is true, also while will re-calculate the data everytime.

We do not use them in the same contexts (true they can be used)

I tend to use foreach most of the time myself because it seems to make more sense for arrays. I thought it was the best way, but I got into an argument with my friend that said I should be using while loops for everything.

foreach is the best when dealing with arrays IMO..

while is good when you are dealing with DB results ..

As NeverMind said, foreach is best when dealing with arrays... but they are also best for doing thing with math (repeating thing values to how many time to display it, or skip stuff in between and etc) while, a while loop is just one standard thing..you can't do much with it.

Hi there,

To add to you guys, especially, when the array is an associative array, foreach() does a terrific job:

PHP Code:

foreach ($myArray as $key => $val) {

      echo 'Key ('.$key.') contains Value: '.$val;

} 

However, though, it's really up to what you are doing. Like some said, when dealing with database resource, while() + fetch() is a good combination or when you don't want the loop to look at "each" of whatever you're looping, then you shouldn't use foreach().

My little comment. =)

Btw, i was taking about the for() loop, not the foreach lol :S (just got a bit mixed up)
